OBJECTIVE:To reflect the representative problems existing in the medication safety of public from the side,and provide reference for conducting the following public survey in a large area. METHODS:Questionnaires were used to investigate the knowledge of drug and medication habits of teachers in a senior high school in Beijing,and the received data was statistically analyzed. RESULTS:Totally 88 questionnaires were issued in this investigation,84 effective questionnaires were acquired,with ef-fective recovery of 95.45%. A few teachers had blind faith in intravenous infusion and preferred using antibiotics without doctor's di-agnosis when they caught a cold and fever;48.81%of the respondents barely understood or only partly understood the drug instruc-tions;34.52% didn't know that more serious adverse reactions induce by intravenous infusion were more serious than by oral treat-ment;46.43% rarely checked the period of validity of reserved drugs at home;38.10% didn’t following directions when taking drugs;80.95% had never received the education of medication safety,and 21.43% of them had no intention to accept this educa-tion;when taking drugs for a long time,79.76% of them didn’t do regular examinations of blood routine,renal and liver function tests. CONCLUSIONS:The knowledge of drug use of the respondents in the school is poor,there are many misunderstandings ex-isted in the medication habit,which prompts hidden trouble also exists in medication safety,and reflects hidden trouble commonly exists in medication safety for public from the side.

BACKGROUND: Dentin particles, tricalcium phosphate/collagen protein composites and Bio-oss particles can repair jaw defects, but the excellent osteogenic effect is not clear. OBJECTIVE: To compare osteogenic effects of three different bone graft materials on mandibular defects in beagle dogs. METHODS: Eight 1-year-old beagles were selected. A boxed bone defect area of 10 mm × 8 mm × 2 mm was prepared at the bilateral mandibular external oblique line and randomly divided into four groups with four bone defect models in each group. Undemineralized dentin particles were implanted in group A; tricalcium phosphate/ collagen protein composite materials were implanted in group B; Bio-oss particles were implanted in group C; and group D was used as blank control. Three months after transplantation, the samples were taken for histological observation. The experimental animals were approved by the Ethics Committee of the Experimental Animal Center of Dalian Medical University. RESULTS AND CONCLUSION: (1) In group A, dentin particles were slightly absorbed, surrounded by new bone tissue; new bone trabeculae and capillaries could be seen, and a large number of fibrous connective tissue surrounded dentin particles in the central area of bone graft. In group B, a small number of new bone trabeculae and osteoblasts could be seen; a large number of powdered β-tricalcium phosphate particles and a small amount of inflammatory cells could be seen in the fibrous connective tissue; and some β-tricalcium phosphate particles were surrounded by new bone tissue. Bone marrow cavity could be seen in the new bone. In group C, some Bio-oss particles were surrounded by new bone tissue; some Bio-oss particles were wrapped by surrounding fibrous connective tissue, and fibers, particles and new bone were intertwined. There was no new bone formation in group D, and many capillaries could be seen in a large number of fibrous connective tissue. (2) The rate of new bone formation in groups A, B and C was higher than that in group D (P < 0.05); the rate in groups A and C was higher than that in group B (P < 0.05). (3) The results show that all the three kinds of bone graft materials can promote the formation of new bone. The short-term osteogenic effects of undecalcified xenogeneic dentin particles and Bio-oss particles are better than tricalcium phosphate/collagen protein composites, but the long-term effects need to be further observed.

Quantitative analysis on diffusion tensor imaging is prerequisite. The arithmetic of statistical analysis was reviewed in this article via analyzing the arithmetic of quantitative parameters and fiber track on diffusion tensor imaging.

OBJECTIVE To observe the efficacy of specific immunotherapy (SIT) with Alutard and NHD in children with allergic rhinitis due to different level of skin prick test (SPT) with dermatophagoides farinae (DF) and dermatophagoides pteronyssinus (DP). METHODS A total of 178 children with persistent allergic rhinitis were included in this study. Their age ranged from 6 to 12 years. They were divided into 3 groups according to level of SPT. Group 1: The level of skin index (SI) of DF is greater than that of DP, Group 2: The level of SI of DF is equal to that of DP and Group 3: The level of SI of DF is less than that of DP. The children in each group were randomly divided into 2 subgroups: Alutard group and NHD group. The children were given SIT with Alutard or NHD for one year. Symptom and medication scores were recorded and analyzed. RESULTS After receiving therapy for 3 months and 6 months, symptom and medication scores of the Group 1 and 2 in the NHD group were lower than those in the Alutard group (P<0.05); Symptoms and medication scores of the Group 3 in the Alutard group were lower than those in the NHD group (P<0.05). After receiving therapy for 9 and 12 months, the symptom and medication scores of the NHD and Alutard group in all the three groups showed no statistical difference (P>0.05). CONCLUSION The efficacy of SIT with Alutard and NHD is different in children with allergic rhinitis with different levels of SPT due to DF and DP after 3 and 6 months, but is similar after 9 and 12 months. SIT with Alutard and NHD is effective in treating children with allergic rhinitis.

BACKGROUND: As a candidate gene of congenital heart disease, ACTC1 gene is related to congenital atrial septal defect inhumans.OBJECTIVE: To perform a mutation screen of ACTC1 gene in 110 nuclear families of congenital heart disease.METHODS: A case-control study was conducted based on 110 nuclear families of congenital heart disease and 300 normalhuman beings with no reported cardiac malformation. Six fragments in the coding region of ACTC1 gene was amplified by PCR invitro using five primers pairs. PCR products were screened for gene mutations.RESULTS AND CONCLUSION: A novel G-to-A variant was found at the third nucleotide of the intron downstream from exon 5.This mutation existed in a 5-year-old female with an isolated ventricular septal defect and her 30-year-old father, who had noreported cardiac anomalies. This mutation was not detected in 300 normal controls. These findings indicate that the mutation maybe related with congenital ventricular septal defects in humans.

Objective To analyze the characteristics of TCM syndromes of children abnormal sweating;To investigate the correlation between diseases and primary and secondary syndromes. Methods Through a multi-center epidemiology investigation, 400 cases were collected to statistically analyze the five TCM syndromes of children abnormal sweating, and characteristics of each syndrome were analyzed. Results In the 400 cases of children abnormal sweating, there were 129 cases (32.25%) of dysfunction of lung-wei pattern, 50 cases (12.50%) of nutrient qi and defensive qi discordance, 84 cases (21.00%) of qi and yin deficiency pattern, 57 cases (14.25%) of dampness heat forced steamed pattern, and 80 cases (20.00%) of qi and yang deficiency pattern. Spontaneous sweating and night sweating were found in the four patterns besides qi and yin deficiency pattern, and night sweating can be mainly found in qi and yin deficiency. Each type is consistent in the syndrome differentiation and cluster analysis. Conclusion Spontaneous sweating and night sweating, each has the certification of yin and yang. Spontaneous sweating can be caused by yin deficiency while night sweating can be caused by yang deficiency. Each pattern of children abnormal sweating has its own syndrome characteristic, which can provide the basis for clinical diagnosis and treatment.
